Oval Sandawana emerald crossing the one carat border and thus counted as full-sized in Sandawana terms. The cutting grade of these gems rarely deserved a better than 'good' as in good -enough' but this is not so much the fault of the cutter. It is rather the hardness (or lack thereof) of all emeralds and the fact that these gems have been cut two decades ago and not also treated carefully ever since (not by us of course). That said, I would not advice re-cuts since these gems, aside from their rarity, will not gain in luster or show since they are valued for the rich color rather than for luster. Both combined color and luster are a rare and far more expensive proposition. Most emerald are included and inclusions break rays of light entering any gem. Choose from our remaining stock, most likely the best and largest inventory available since the Sandawana mines have been closed. Though alone full-sized, meaning rings up to US size ten, we may be able to make a matching pair.
Possibly pairing with PEP067
P.S. The unusual circumstances of this year, personal and in general, have so far hindered us from getting lab reports done, although I dare hope this will change by late May when I will visit Antwerp in person. The price here quoted is EXCLUDING our usual certificate. If you like to have a lab report for this emerald we need to add between $100 for a full IGI report or up to $1,000 for a premium AIG report. It would need a good deal extra time (currently over 12 weeks, sigh). That lab prices in this P.S. section differ is no lazy mistake but reflects the different pricing policies of the gem labs we use. Some calculate via weight, e.g. a 7 carat garnet is more expensive to test than a one carat, others labs go via pieces, when a small sapphire costs as much as a 10 carat gem.
Discuss design options (with a matched pair possible)

I imagine, even good old Brad had a hard time getting these, estimated at 4ct/each.
